Given the economic growth and energy consumption patterns, most countries are striving to solve the problems of CO emissions reduction to achieve sustainable development. This paper employs an improved DEA model to measure energy and environmental efficiency for some selected countries in central and western Europe. In addition, the DEA window evaluation technique is applied to measure cross-sectional efficiency using two inputs (energy consumption, labor force), a desirable output (gross domestic product), and an undesirable output (CO emission) for the period from 2010 to 2014. The study finds that the UK ranks the highest position in term of energy and environmental efficiency. This shows that the UK has more effective policies regarding energy efficiency, consumption, production, import and energy intensity measures for sustainable economic growth as well as environmental protection. Ireland is the second-best country after the United Kingdom. The efficiency scores of the two countries are 0.99 and 0.89 respectively. On the empirical outcomes, this study suggests effective reforms in energy sector for countries with less energy efficiency that are still facing the problem of environmental degradation.
鉴于经济增长和能源消费模式，大多数国家都在努力解决 CO 减排问题，以实现可持续发展。本文采用改进的 DEA 模型来衡量中欧和西欧部分国家的能源和环境效率。此外，使用 DEA 窗口评估技术，在 2010 年至 2014 年期间，使用两个投入（能源消耗、劳动力）、一个期望产出（国内生产总值）和一个非期望产出（CO 排放）来衡量横截面效率。研究发现，英国在能源和环境效率方面排名最高。这表明英国在能源效率、消费、生产、进出口以及能源强度措施方面有更有效的政策，以实现可持续的经济增长和环境保护。爱尔兰是继英国之后的第二大最佳国家。这两个国家的效率得分分别为 0.99 和 0.89。在实证结果方面，本研究建议能源效率较低且仍面临环境退化问题的国家在能源部门进行有效的改革。
